I’m on 5.3 now and it seems to work fine with no hacks to the project settings. It’s a 10FPS hit over using a home grown crowd of Manny characters. It also seems to get lost at times if a character wavers slightly and walks in place while working around an object. Each character that does that will be off by the time they kept walking but stood in place. Then it requires a restart to get them to follow the spline track they were supposed to be on. The net effect is that CSC pawn that was supposed to be walking on the sidewalk, will end up out in the street. I could be making a mistake in setup, but I don’t think it’s production ready. When it works, it looks great though.
Edit: my comment that it wasn’t production ready was too harsh. What I really meant was that wide corridors for the spline are required to keep the pawns from momentarily freezing on a collider, as when they do, they lose precision in following the spline which appears to never be reset/recovered. Admittedly, I never tried putting the component on the buildings they would occasionally wander into and thus avoid a situation where they would continue walking without forward progress. In an open area, they work great.
